A Framework for Code Division Multiple Access Wireless Power Transfer

IEEE Access, 2021
The availability of energy is one of the major hindrances to unlocking the massive potential of electronic devices. Powering a highly connected network of devices requires multiple access and a wireless power transfer (WPT) solution that is scalable and ...

CDMA/OTFS Sensing Outperforms Pure OTFS at the Same Communication Throughput

IEEE Open Journal of Vehicular Technology
There is a dearth of publications on the subject of spreading-aided Orthogonal Time Frequency Space (OTFS) solutions, especially for Integrated Sensing and Communication (ISAC), even though Code Division Multiple Access (CDMA) assisted multi-user OTFS ...

A Complementary Code-CDMA-Based MAC Protocol for UWB WPAN System

EURASIP Journal on Wireless Communications and Networking, 2005
We propose a new multiple access control (MAC) protocol based on complementary code-code division multiple access (CC-CDMA) technology to resolve collisions among access-request packets in an ultra-wideband wireless personal area network (UWB WPAN ...

Carrier Sense Random Packet CDMA Protocol in Dual-Channel Networks [PDF]

Radioengineering, 2015
Code resource wastage is caused by the reason that many hopping frequency (FH) sequences are unused, which occurs under the condition that the number of the actual subnets needed for the tactical network is far smaller than the networking capacity of ...

Performance analysis of unslotted fiber-optic code-division multiple-access (CDMA) packet networks [PDF]

IEEE Transactions on Communications, 1997
Summary: This paper examines code-division multiple-access (CDMA) techniques used in slotted fiber-optic packet networks. Since the inherent properties and signal processing of the conventional communication channels are different from those of the fiber-optic channels, new code sequences must be constructed for fiber-optic applications.

New Difference Triangle Sets by a Field‐Programmable Gate Array‐Based Search Technique

Journal of Combinatorial Designs, Volume 34, Issue 1, Page 37-50, January 2026.
ABSTRACT We provide some difference triangle sets with scopes that improve upon the best known values. These are found with purpose‐built digital circuits realized with field‐programmable gate arrays (FPGAs) rather than software algorithms running on general‐purpose processors.

Mixer‐Based Neural Network for Binary Sequence Generation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes MixBinNet, a neural network‐based model for generating binary sequences with low autocorrelation sidelobes, low cross‐correlation and balanced bit distributions. By jointly optimizing these properties through custom loss functions, MixBinNet outperforms conventional chaotic map‐based methods, achieving improved correlation ...
